fields of application: 2D graphics, sound, file system operations, text output, animations, sprites, layers, transition effects, image manipulation, saving of images and video files, time and date functions, input functions (keyboard, joystick, mouse) as well as mathematical operations and string functions. Programming in Hollywood is done via so called Hollywood scripts (using the file extension *.hws). These scripts are compiled dynamically and can be converted into stand-alone executables. All Hollywood programs run inside a sandbox, which makes it impossible for them to crash. Platform independence Hollywood was designed to be a completely platform independent programming language. Thus, scripts cannot call any API functions of the host operating system directly and are limited to the inbuilt command set. Text rendering is also implemented via a platform independent font backend that ensures that TrueType text looks exactly the same on every platform. Furthermore, all versions of Hollywood support Amiga specific file formats like IFF ILBM images, IFF 8SVX sounds, or IFF ANIM files, to be fully compatible with scripts written on an Amiga system. GUI development There are several GUI toolkits for Hollywood. RapaGUI is a cross-platform GUI plugin for Hollywood which supports Windows, macOS, Linux, and AmigaOS. RapaGUI uses native GUI controls provided by the respective host operating system giving all RapaGUI applications a native look and feel. MUI Royale is a GUI toolkit for Hollywood which can be used to create GUIs using the Magic User Interface. Another GUI toolkit for Hollywood is HGui. In contrast to RapaGUI and MUI Royale, HGui draws its GUI controls itself which makes its graphical user interfaces look exactly the same on every platform. Compiler A special feature of the cross-platform compiler that comes with Hollywood is the ability to link all external files (including fonts) into the executable to be built automatically. This makes it possible to create programs which consist only of a single file and can thus be easily transported and distributed. Additionally, the Hollywood compiler can compile scripts into Hollywood applets (using the file extension *.hwa). These applets are smaller than regular Hollywood programs, but they can only be started on systems that have Hollywood installed. Finally, it is also possible to export Hollywood scripts as AVI videos. Development environment There is no integrated development environment for the Amiga-compatible version of Hollywood. On these systems, Cubic IDE and Codebench can be used to develop with Hollywood as these have support
